Hello. I believe we can help, but we will need to see what is attached to the end of the cord that comes out of your balance. Once you show us this attachment, preferably removed from the window, we should be able to narrow this down for you. Many thanks. |
No problem Casey! Thanks.
In the attached photo you can see the part of the window that is no longer going up when the window is raised. This causes or allows the window to slide down after being raised and this is the problem I am trying to solve.
In browsing around your website, I think this must be a series 751 if it is anything you offer. This is a tilting window from Loewen. Delivered to the construction site in 2006. I have a copy of the order paperwork and THINK I know which is this window if that helps.
BTW - the unit pictured, maybe called a knife lock, does move as sometimes I see it a bit higher and sometimes a bit lower. And when moving the window up/down I sometimes here a twanging noise that I presume is a spring vibrating or something like that. Thanks again.Cheers!
In trying to get more information, I have measured the length of the balances. It turns on that the inner sash balance and the outer have different sized balances with different numbers.
The inner sash, marked 22 DH BSL RP, is 23" from the bottom of the stop (which is 1-3/16 in length and similar to your Product Code: 55-110)/top of the balance to the bottom edge.
The outer sash, marked 20 HD BSL RE, is 21" from the top of the balance to the bottom edge. There is no stop on the outer sash, just a piece of some sort of foam pad.
Hope this helps zero-in on what I need.
Thanks for your time and help.
PS:
Having not actually yet tried to remove the jamb liner (seems not really a good idea until I have replacements in hand), I have no measurements for the balance or the channel it must slide into. However, the exposed face of the balance, where the numbers are stamped, is right around 7/16". Are these dimensions fairly standard with Loewen and across the industry? Thanks

Yes, it looks like you have S751-23 and S751-21 (for the 21" ones) ribbed balances. The spring weights will be 22HD and 20HD, respectively. I think you were correct to identify the Series and weights the way you did. To eliminate the twanging noise when operating the window, use some silicone spray on the vinyl track. That should help. |

Great, glad to hear things are starting to improve. As for where to spray, I recommend removing the balance entirely to spray the spring in the balance itself. You could also apply white grease to the spring. |
